I have this X60s board (with Core Solo U1300 CPU) with a bad fan on my shelf for the longest time, and a battered X60 chassis (with working heatsink and fan)... so I went ahead and put the two together.

The amusing results:
1. CPU temperature hovers around 50c, even at ~70% CPU utilization according to Task Manager.

2. The palmrest is hotter than the heatsink's exhaust-- I'm still using the stock Intel 3945BG wifi as I haven't flashed Zender's BIOS yet.

With wifi on and running Firefox, it's reporting an estimated 167 minutes runtime.
Note that I haven't undervolted it yet, as I don't have linux-phc compiled-- the kernel module needed for undervolting is out-of-tree, and has lots of dependencies I don't want to install on the 32GB SSD I'm currently using.

If the estimate is accurate, it would run in excess of 5 hours on a new, original 74 Wh 8-cell battery.

Flashed Zender via Windows (temporarily installed HDD from another X60 that that Windows 7). After installing the AR9485 wifi card, it's detected in Linux, but the WiFi radio doesn't turn on.

I'm pretty sure this is one of those "tape Pin 20" issues, but I'd rather not tape it, as I want to be able to disable it when I need to.
Which means I'll have to test the other WiFi cards I have in storage to see which one works without taping. :I

Finally found a card that works. It's a Broadcom BCM4313 BGN (2.4GHz) [14e4:4727]. Getting it to work on Linux took a bit of fiddling, as I wasn't sure which kernel driver to use (there's at least 3 drivers for the b43 series).

Debian loaded wl (binary-only driver) by default, but wouldn't detect any networks, so I blacklisted it and used brcmsmac instead. Since it doesn't load automatically, I added it to /etc/modules.
